PURPOSE:To obtain an active carbon having good absorbing characteristics after endurance in good yield by subjecting a mixture of active carbon raw material, porous material and binder to molding, carbonization and activation. CONSTITUTION:1 pts.wt. active carbon raw material (e.g. coal) is blended with 0.05-0.2 pts.wt. porous material (e.g. active alumina) and binder (e.g. pitch) and the blend is molded in a prescribed form, carbonized and then activated to provide the active carbon having many traditional pores not less than 20Angstrom pore radius. |
